PORT LIGHT.

Application filed January 23, 1928. Serial No. 248,609.

This invention relates to a port light for vessels.

The object of the. invention is to provide a novel, simplified andattractive construction of port lightl which may be economicallymanufactured and in which` the cover member or door may be easily andconveniently opened and closed and locked and unlocked in its closedposition. y

A further and more specific object 'of the invention is to provide anovel construction of port light iny which provision is made formaintaining the cover member or door yin different open positions in anovel and simple manner.

With these objects in view and such others as may hereinafter appear,the in,- vention consists in the port light and in the structures,arrangements and combinations` of parts hereinafter' described andparticularly defined in the'claims aty the end of this specification. A

In the drawings illustrating the preferred embodiment of the invention,Figure l is a front elevation of the improved portflight; Fig. 2 is apart section and partl plan, the section being taken on line 2-2'of Fig.1; Fig. 3 is a sectional detail on the liner 3-3 of Fig. 1; Fig. l is adetail to be referred to; and F ig. 5 is a sectional detail of thesleeve and operating handle forming a part of the port light.

Various constructions of port'lights have been heretofore proposedinvolving more or less complicated constructions with which the coversor doors ycould in practice be opened and closed7 only with difficulty.The present invention contemplates a port light of a simplifiedconstruction which may be manufactured at minimum cost and in which thecover member may be opened and closed and also locked and unlockedinvits closed position with much more Aconvenience and ease than otherprior constructions of port lights of which l am aware. lProvision ismade for maintaining anl efcient watertight seal between the covermember and the body of the 'port light when the'cover member is closedand locked. Provision is also preferably made for securing the door orcover `member of the port lightin differn ent open positions in a novelyand simplified is formed with rarear portion 16 designed to lit intothe hole l1 and also a forward portion 17 extending in front of theflange 111,'and the end surface 'of the forwardportion 17 of the'lhubis` preferably provided with an annular recess thereinl 'for the revtenti'on ofa body 18 of resilient waterproof material such asrubber7 astrip of the latf ter] preferably being inset and cemented in therecess. n j

The port light is further provided with aV cover member 2O hereinshownfas a cast ring provided with ears 22, which cooperate with ears'23 formed upon and projecting forwardly from ythe surface of the flange14; to pivotally support the cover member 20 upon the flange by means ofa pivot bolt 24: as shown. The cover member 20 is provided with a glassplate 26 secured within the cover 2O by a threaded retaining ring 28 asillustrated in Fig. `2. The interior of the cover ring 2O is alsopreferably 'provided witha vraised portion 30, whose opposite lsurfacesare tapered or beveled to enablefit tofengage the rubber ystrip 18` andto ber drawn tightly against thesame within the annular recess intheendof the forward portion 17 of the hub 10, by the action of a lockingdevice to be described, thereby providing a water tight seal for theport light.

Provision is made for holding the cover member 20 in'its closed positionwithk the y,raised kportion 30 kwithin they cover ring,

pressed against the rrubber strip 18,` as illustrated'in Fig. 2, torender the port light water tight, rand for this purpose as herein shownthe interior of the cover member 20 is provided with a plurality of lugswhich are spaced at invervals around the cover memberand at a suficientdistance from one another to permit corresponding lugs 42 upon theperiphery of the sleeve 35 to pass through said spaces when the covermember ismoved vinto a closed position. The adjacent'surfaces of thelugs 40, 42 are beveled to provide cooperating cam surfaces, one ofwhich is shown at 44,'and which are arranged so that-when the sleeve 35is rotated by means of an operating -handle 46 from a position in whichthe handle abuts a stop pin 48 in the flange 14, to a position such asisshown in full lines in Fig. 1, the corresponding pairsof lugs 40, 42through the` cooperating cam surfaces 44 cause the cover member to bedrawn toward the lflange 14 so that the port-ion 30 presses tightlyagainst the rubber sealing ring, 18, as shown in Fig. 2-. Thecooperating lugs 40, 42 upon the cover member and sleeve 35 respectivelyconstitute locking members which effectively serve to retain or lockthe. cover in its closed position until such time as the handle 46 isagainv returned to a position abuttino' the stop pin 48.

- In order to hold the cover member 2O lof the portlight in diierentopen positions,

provision is preferably made for locking the cover in various openpositions, and as herein shown alocking pin 50 having an operatinghandle 52 is normally urged by a spring 53 within a fitting 54 screwedvinto a hole in one of lthe earsf23, into one of several holes 55 formedin the lower ear 22.

,In opening the port light the operator observed that the presen-t portlight presents a vvery attractive appearance, adding considerably to theappearance of the stateroom or other portion of the vessel in which itmay be located, and that the port lightdoor or cover may be opened orclosed in a minimum time and with minimum eifort. The construction ofthe' port light is such that an etiicient water tight seal is providedwhen the cover or door is closed and locked, and in addition therelatively few parts entering into the design of the port lightfacilitates they economical .manufacture thereof.

W'hile the preferred embodiment of the invention has been illustratedand described, it is to be understood that the invention may be embodiedin other forms within the scope of the following claims.

Having thus described the invention what is claimed is 1. A port .lightcomprising a supporting member adapted to be secured to the shipsplating and provided with an opening, a cover member for closing theopening, and means for securing the cover member in its closed positionincluding a locking member upon theA interior of the cover, a secondlocking member for cooperating therewith, a threaded connection betweenthe second locking member and the supporting member whereby uponrotation the second locking member is moved into engagement with theirst and in a direction toward the supporting member.

2. A port light comprising a supporting member adapted to be secured tothe ships plating and provided with an opening and a hub surroundingythe opening, a cover member pivoted to the supporting member andadapted to close the opening, and means for securing the cover` memberin its closed position including a locking member upon the interior ofthe cover member, a rotatable sleeve screwed upon said hub and providedwith a locking member adapted to engage the locking member upon thecover when the sleeve is rotated in one direction and to thereby drawthe cover member into engagement with ythe hub to close the opening. f f
